Definitions

  • the invention relates to inhibitors of diacylglycerol acyltransferase.
  • the inhibitors are amide and urea derivatives which are useful for the treatment of diseases such as obesity, type II diabetes mellitus and metabolic syndrome.
  • Obesity is characterized by an excessive adipose tissue mass relative to body size.
  • body fat mass is estimated by the body mass index (BMI; weight(kg)/height(m) 2 ), or waist circumference.
  • BMI body mass index
  • Individuals are considered obese when the BMI is greater than 30 and there are established medical consequences of being overweight. It has been an accepted medical view for some time that an increased body weight, especially as a result of abdominal body fat, is associated with an increased risk for diabetes, hypertension, heart disease, and numerous other health complications, such as arthritis, stroke, gallbladder disease, muscular and respiratory problems, back pain and even certain cancers.
  • Drugs aimed at the pathophysiology associated with insulin dependent Type I diabetes and non-insulin dependent Type II diabetes have many potential side effects and do not adequately address the dyslipidaemia and hyperglycaemia in a high proportion of patients. Treatment is often focused at individual patient needs using diet, exercise, hypoglycaemic agents and insulin, but there is a continuing need for novel antidiabetic agents, particularly ones that may be better tolerated with fewer adverse effects.
  • metabolic syndrome which is characterized by hypertension and its associated pathologies including atherosclerosis, lipidemia, hyperlipidemia and hypercholesterolemia have been associated with decreased insulin sensitivity which can lead to abnormal blood sugar levels when challenged.
  • Myocardial ischemia and microvascular disease is an established morbidity associated with untreated or poorly controlled metabolic syndrome.
  • DGAT Diacylglycerol O-acyltransferase
  • DAG 1,2-diacylglycerol
  • DGAT plays an essential role in the metabolism of cellular diacylglycerol and is important for triglyceride production and energy storage homeostasis (Mayorek et al, European Journal of Biochemistry (1989) 182, 395-400).
  • DGAT1 and DGAT2 Two forms of DGAT have been cloned: DGAT1 and DGAT2 (Cases et al, Proceedings of the National Academy of Science, USA (1998) 95, 13018-13023, Lardizabal et al, Journal of Biological Chemistry (2001) 276, 38862-38869 and Cases et al, Journal of Biological Chemistry (2001) 276, 38870-38876).
  • both enzymes utilize the same substrates, there is no significant homology between DGAT1 and DGAT2. Further, although both enzymes are widely expressed, differences exist in the relative abundance of DGAT1 and DGAT2 expression in various tissues.
  • DGAT1 knock-out mice do not become obese when challenged with a high fat diet in contrast to wild-type littermates (Smith et al., Nature Genetics 25:87-90, 2000).
  • DGAT1 knock-out mice display reduced postprandial plasma glucose levels and exhibit increased energy expenditure, but have normal levels of serum triglycerides (Smith et al., 2000), possibly due to the preserved DGAT2 activity. Since DGAT1 is expressed in the intestine and adipose tissue (Cases et al., 1998), there are at least two possible mechanisms to explain the resistance of DGAT1 knock-out mice to diet induced obesity.

Description

    BACKGROUND OF THE INVENTION
  • The invention relates to inhibitors of diacylglycerol acyltransferase. The inhibitors are amide and urea derivatives which are useful for the treatment of diseases such as obesity, type II diabetes mellitus and metabolic syndrome.
  • Obesity is characterized by an excessive adipose tissue mass relative to body size. Clinically, body fat mass is estimated by the body mass index (BMI; weight(kg)/height(m)2), or waist circumference. Individuals are considered obese when the BMI is greater than 30 and there are established medical consequences of being overweight. It has been an accepted medical view for some time that an increased body weight, especially as a result of abdominal body fat, is associated with an increased risk for diabetes, hypertension, heart disease, and numerous other health complications, such as arthritis, stroke, gallbladder disease, muscular and respiratory problems, back pain and even certain cancers.
  • Pharmacological approaches to the treatment of obesity have been mainly concerned with reducing fat mass by altering the balance between energy intake and expenditure. Many studies have clearly established the link between adiposity and the brain circuitry involved in the regulation of energy homeostasis. Direct and indirect evidence suggest that serotonergic, dopaminergic, adrenergic, cholinergic, endocannabinoid, opioid, and histaminergic pathways in addition to many neuropeptide pathways (e.g. neuropeptide Y and melanocortins) are implicated in the central control of energy intake and expenditure. Hypothalamic centres are also able to sense peripheral hormones involved in the maintenance of body weight and degree of adiposity, such as insulin and leptin, and fat tissue derived peptides.
  • Drugs aimed at the pathophysiology associated with insulin dependent Type I diabetes and non-insulin dependent Type II diabetes have many potential side effects and do not adequately address the dyslipidaemia and hyperglycaemia in a high proportion of patients. Treatment is often focused at individual patient needs using diet, exercise, hypoglycaemic agents and insulin, but there is a continuing need for novel antidiabetic agents, particularly ones that may be better tolerated with fewer adverse effects.
  • Similarly, metabolic syndrome (syndrome X) which is characterized by hypertension and its associated pathologies including atherosclerosis, lipidemia, hyperlipidemia and hypercholesterolemia have been associated with decreased insulin sensitivity which can lead to abnormal blood sugar levels when challenged. Myocardial ischemia and microvascular disease is an established morbidity associated with untreated or poorly controlled metabolic syndrome.
  • There is a continuing need for novel antiobesity and antidiabetic agents, particularly ones that are well tolerated with few adverse effects.
  • Disorders or imbalances in triglyceride metabolism have been implicated in the pathogenesis of a variety of disease risks, including obesity, insulin resistance syndrome, type II diabetes, metabolic syndrome (syndrome X) and coronary heart disease.
  • Diacylglycerol O-acyltransferase (DGAT) is a key enzyme in triglyceride synthesis. DGAT catalyzes the final and rate limiting step in triacylglycerol synthesis from 1,2-diacylglycerol (DAG) and long chain fatty acyl CoA as substrates. Thus, DGAT plays an essential role in the metabolism of cellular diacylglycerol and is important for triglyceride production and energy storage homeostasis (Mayorek et al, European Journal of Biochemistry (1989) 182, 395-400).
  • Two forms of DGAT have been cloned: DGAT1 and DGAT2 (Cases et al, Proceedings of the National Academy of Science, USA (1998) 95, 13018-13023, Lardizabal et al, Journal of Biological Chemistry (2001) 276, 38862-38869 and Cases et al, Journal of Biological Chemistry (2001) 276, 38870-38876). Although both enzymes utilize the same substrates, there is no significant homology between DGAT1 and DGAT2. Further, although both enzymes are widely expressed, differences exist in the relative abundance of DGAT1 and DGAT2 expression in various tissues.
  • DGAT1 knock-out mice do not become obese when challenged with a high fat diet in contrast to wild-type littermates (Smith et al., Nature Genetics 25:87-90, 2000). DGAT1 knock-out mice display reduced postprandial plasma glucose levels and exhibit increased energy expenditure, but have normal levels of serum triglycerides (Smith et al., 2000), possibly due to the preserved DGAT2 activity. Since DGAT1 is expressed in the intestine and adipose tissue (Cases et al., 1998), there are at least two possible mechanisms to explain the resistance of DGAT1 knock-out mice to diet induced obesity. First, abolishing DGAT1 activity in the intestine may block the reformation and export of triacylglycerol from intestinal cells into the circulation via chylomicron particles. Second, knocking out DGAT1 activity in the adipocyte may decrease deposition of triacylglycerol in the white adipose tissue.
  • Compounds that decrease the synthesis of triglycerides from diacylglycerol by inhibiting or lowering the activity of the DGAT1 enzyme are predicted to be of value as therapeutic agents for the treatment diseases associated with abnormal metabolism of triglycerides. Thus a need exits for additional DGAT1 inhibitors that have efficacy for the treatment of metabolic disorders such as, for example, obesity, type II diabetes mellitus and metabolic syndrome.

  • Examples of leaving groups include halogen e.g. Cl. Further leaving groups include carbamate leaving groups i.e. where LG=ORc wherein Rc is typically an aromatic moiety such as substituted phenyl especially 4-nitrophenyl.
  • Formation of the amide by reaction of compounds of formula (II) and (III) or protected derivatives thereof may be facilitated by use of a coupling reagent such as WSC or HATU. Alternatively compounds of formula (III) may be employed in the form of an activated derivative thereof such as an acid halide or acid anhydride. Such activated derivatives may be obtained from the corresponding acid by conventional means. When a compound of formula (III) is employed as an acid halide, it may suitably be reacted with a compound of formula (II) in an inert aprotic solvent such as THF in the presence of a base such as TEA.
  • Compounds of formula (II) and (IIIA) or (IIIB) may suitably be combined in an inert solvent such as THF at room or elevated temperature.

Thus compounds of formula (I) in which Z represents OH or else the Z group comprises a COOH moiety may be prepared by deprotection, e.g. hydrolysis, of a corresponding compound in which said Z group is protected, for example as an ester such as an alkyl, e.g. methyl or ethyl, ester.
  • Compounds of formula (II) or a protected derivative thereof in which Y represents a bond and R3 represents hydrogen may be prepared by the route shown in Scheme 1 below:

  • In Scheme 1, Z′ represents —NR6R7 or —OR wherein R is an ester forming group as described above.
  • Thus, an appropriately substituted cyclohexanone such as (VII) can be converted to the corresponding triflate (VI) via quenching of the intermediate enolate with a triflating agent such as N-phenyl triflamide. The enolate could be generated by addition of a base such as lithium diisopropylamide, typically at low temperature. Triflate (VI) can be reacted with an appropriately substituted aryl or heteroaryl boronic acid under Suzuki coupling conditions to afford cyclohexene (IV). A Suzuki coupling typically utilises a palladium catalyst in the presence of a base e.g. potassium carbonate in a solvent such as ethanol or dioxane, or in a mixture of solvents such as ethanol/water. If desired, the triflate (VI) can be converted to boronic ester (V) by reaction with bis-pinacolato-diborane in the presence of a base and palladium catalyst. Boronic ester (V) can then be reacted with an appropriately substituted aryl or heteroaryl bromide or iodide, again under Suzuki coupling conditions, to afford cyclohexene (IV). Cyclohexene (IV) can be reduced to an aniline of type (II) by, for example, reaction with hydrogen gas under palladium catalysis. This reaction could afford a mixture of stereoisomers which may be separated, if desired, as outlined previously.

  • Nitrobenzene (VIII) can be reduced to aniline (II) by a variety of techniques such as hydrogenation in the presence of a palladium catalyst. If R1 and/or R2 are a halogen such as chlorine, a platinum catalyst may be employed to mitigate dehalogenation.
  • The corresponding nitro compounds of formula (VIII) may be prepared following Scheme 3 outlined below:
  • Figure US20100093733A1-20100415-C00007
  • In Scheme 3, Z″ represents OR wherein R is an ester forming group as described above.
  • Homologation of cyclohexanone (XII) under Wittig or Horner-Wadsworth-Emmons conditions could afford enol ethers of type (XI).

For examples esters may be prepared in one pot using Oxone™ in a suitable alcoholic solvent. Stereoisomers (VIII′) and (VIII″) can be separated using standard laboratory techniques such as column chromatography or recrystallisation. Stereochemistry can be ascertained by appropriate NMR techniques.
  • Compounds of formula (XII) may be prepared following Scheme 4 below:
  • Figure US20100093733A1-20100415-C00008

  • Compounds of formula (II) in which Y represents CH2 and R3 represents hydrogen may be prepared following Scheme 5:
  • Figure US20100093733A1-20100415-C00009
  • In Scheme 5, Z″ represents OR wherein R is an ester forming group as described above.
  • Homologation of cyclohexanone (XIV) under appropriate Wittig or Horner-Wadsworth-Emmons conditions could afford α,β-unsaturated ester (XVI). Reduction of the nitro group and double bond to yield aniline (II) could be carried out in one step, if desired, under catalytic hydrogenation conditions in the presence of a palladium catalyst. Aniline (II) may be obtained as a mixture of stereoisomers, which could be separated as outlined above.
  • Compounds of formula (II) in which Y represents (CH2)2 and (CH2)3 and R3 represents hydrogen may be prepared following Scheme 6 below:
  • Figure US20100093733A1-20100415-C00010
  • In Scheme 6, Z″ represents OR wherein R is an ester forming group as described above. Anilines of type (XVI) where M is a bond or methylene linker can be prepared from aldehyde (X) as outlined in Scheme 6. Homologation of aldehyde (X) under appropriate Wittig or Horner-Wadsworth-Emmons conditions could afford unsaturated ester (XV). Conversion to (XVI) can be carried out under catalytic hydrogenation conditions in the presence of, for example, a palladium catalyst.
  • Further nitro intermediates which may be used in the preparation of compounds of formula (II), e.g. intermediates of type (XVII) and (XVIII) where R3 is hydroxy or C1-C3 alkoxy, can be prepared as outlined in Scheme 7 below, where Rt represents C1-C3 alkyl and Z″ is as described above:
  • Figure US20100093733A1-20100415-C00011
  • Addition of the lithium salt of methyl acetate to cyclohexanone (XII) would afford β-hydroxyester of type (XVII) as a mixture of stereoisomers. Alkylation of (XVII) with alkyl iodide (Rt—I) in the presence of a base could afford β-alkoxyesters of type (XVIII). Rt is, for example, methyl. If desired, stereoisomers could be separated by standard laboratory techniques. Compounds of type (XVIII) could be converted to the corresponding anilines by reduction of the nitro group employing, for example, hydrogenation in the presence of a palladium catalyst.
  • Further nitro intermediates of type (XX) and (XXI) where Rt represents C1-C3 alkyl can be prepared as outlined in Scheme 8 below:

  • Reaction of cyclohexanone (XII) with methyl acrylate in the presence of samarium (II) iodide could afford lactone (XIX). Hydrolysis of this lactone with, for example, sodium hydroxide would afford hydroxy acid (XX) which could be alkylated with an alkyl iodide (RtI) in the presence of base, to yield alkoxy acids of type (XXI).
  • Nitro intermediates of formula (XXIII) or a protected derivative thereof in which Y represents —O(CH2)n(CR10R13)o(CH2)p— may be prepared as shown in Scheme 9 below:

This anion can be quenched with an alkyl halide such as methyl iodide to afford the α-alkyl ester. This protocol can be repeated to install a second alkyl group. Alternatively, if the alkyl halide contains two suitably placed halides, such as 1,3-dibromopropane, then a carbocylic ring can be installed adjacent to the ester group by this procedure.

  • Compounds of formula (XXVII) and (XXVIII) may be prepared from compounds of formula (II) by an analogous process to that described above for the preparation of compounds of formula (IIIA) and (IIIB) from compounds of formula (IIIC). Thus compounds of formula (XXVII) may be prepared from compounds of formula (II) by known methods, for example carbamoyl chlorides (compounds of type (XXVIII) where LG is chlorine) may be prepared by reacting compounds of formula (II) with phosgene. Carbamoyl chlorides can lose hydrogen chloride to form isocyantes. Compounds of formula (XXVIII) may be prepared from compounds of formula (II) by known methods, for example when LG is a substituted phenol, carbamates can be prepared by reacting compounds of formula (II) with substituted phenyl chloroformates.

  • During the synthesis of the compounds of formula (I), labile functional groups in the intermediate compounds, e.g. hydroxy, carboxy and amino groups, may be protected. The protecting groups may be removed at any stage in the synthesis of the compounds of formula (I) or may be present on the final compound of formula (I). A comprehensive discussion of the ways in which various labile functional groups may be protected and methods for cleaving the resulting protected derivatives is given in, for example, Protective Groups in Organic Chemistry, T. W. Greene and P. G. M. Wuts, (1991) Wiley-Interscience, New York, 2nd edition.

  • Moreover, the invention also provides a pharmaceutical composition for the treatment of disease by inhibiting DGAT1, e.g. resulting in the treatment of obesity, comprising a pharmaceutically acceptable carrier and a non-toxic therapeutically effective amount of compound of formula (I), or a pharmaceutically acceptable salt thereof.
  • The pharmaceutical compositions may optionally comprise other therapeutic ingredients or adjuvants. The compositions include compositions suitable for oral, rectal, topical, and parenteral (including subcutaneous, intramuscular, and intravenous) administration, although the most suitable route in any given case will depend on the particular host, and nature and severity of the conditions for which the active ingredient is being administered. The pharmaceutical compositions may be conveniently presented in unit dosage form and prepared by any of the methods well known in the art of pharmacy.
  • In practice, the compounds of formula (I), or pharmaceutically acceptable salts thereof, can be combined as the active ingredient in intimate admixture with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques. The carrier may take a wide variety of forms depending on the form of preparation desired for administration, e.g. oral or parenteral (including intravenous).
  • Thus, the pharmaceutical compositions can be presented as discrete units suitable for oral administration such as capsules, cachets or tablets each containing a predetermined amount of the active ingredient. Further, the compositions can be presented as a powder, as granules, as a solution, as a suspension in an aqueous liquid, as a non-aqueous liquid, as an oil-in-water emulsion, or as a water-in-oil liquid emulsion. In addition to the common dosage forms set out above, the compound of formula (I), or a pharmaceutically acceptable salt thereof, may also be administered by controlled release means and/or delivery devices. The compositions may be prepared by any of the methods of pharmacy. In general, such methods include a step of bringing into association the active ingredient with the carrier that constitutes one or more necessary ingredients. In general, the compositions are prepared by uniformly and intimately admixing the active ingredient with liquid carriers or finely divided solid carriers or both. The product can then be conveniently shaped into the desired presentation.
  • The compounds of formula (I), or pharmaceutically acceptable salts thereof, can also be included in pharmaceutical compositions in combination with one or more other therapeutically active compounds.
  • The pharmaceutical carrier employed can be, for example, a solid, liquid, or gas. Examples of solid carriers include lactose, terra alba, sucrose, talc, gelatin, agar, pectin, acacia, magnesium stearate, and stearic acid. Examples of liquid carriers are sugar syrup, peanut oil, olive oil, and water. Examples of gaseous carriers include carbon dioxide and nitrogen.
  • In preparing the compositions for oral dosage form, any convenient pharmaceutical media may be employed. For example, water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents, and the like may be used to form oral liquid preparations such as suspensions, elixirs and solutions; while carriers such as starches, sugars, microcrystalline cellulose, diluents, granulating agents, lubricants, binders, disintegrating agents, and the like may be used to form oral solid preparations such as powders, capsules and tablets. Because of their ease of administration, tablets and capsules are the preferred oral dosage units whereby solid pharmaceutical carriers are employed. Optionally, tablets may be coated by standard aqueous or nonaqueous techniques.
  • A tablet containing the composition of this invention may be prepared by compression or molding, optionally with one or more accessory ingredients or adjuvants. Compressed tablets may be prepared by compressing, in a suitable machine, the active ingredient in a free-flowing form such as powder or granules, optionally mixed with a binder, lubricant, inert diluent, surface active or dispersing agent. Molded tablets may be made by molding in a suitable machine, a mixture of the powdered compound moistened with an inert liquid diluent. Each tablet preferably contains from about 0.05 mg to about 5 g of the active ingredient and each cachet or capsule preferably containing from about 0.05 mg to about 5 g of the active ingredient.
  • For example, a formulation intended for the oral administration to humans may contain from about 0.5 mg to about 5 g of active agent, compounded with an appropriate and convenient amount of carrier material which may vary from about 5 to about 95 percent of the total composition. Unit dosage forms will generally contain between from about 1 mg to about 2 g of the active ingredient, typically 25 mg, 50 mg, 100 mg, 200 mg, 300 mg, 400 mg, 500 mg, 600 mg, 800 mg, or 1000 mg.
  • Pharmaceutical compositions of the present invention suitable for parenteral administration may be prepared as solutions or suspensions of the active compounds in water. A suitable surfactant can be included such as, for example, hydroxypropylcellulose. Dispersions can also be prepared in glycerol, liquid polyethylene glycols, and mixtures thereof in oils. Further, a preservative can be included to prevent the detrimental growth of microorganisms.
  • Pharmaceutical compositions of the present invention suitable for injectable use include sterile aqueous solutions or dispersions. Furthermore, the compositions can be in the form of sterile powders for the extemporaneous preparation of such sterile injectable solutions or dispersions. In all cases, the final injectable form must be sterile and must be effectively fluid for easy syringability. The pharmaceutical compositions must be stable under the conditions of manufacture and storage; thus, preferably should be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g. glycerol, propylene glycol and liquid polyethylene glycol), vegetable oils, and suitable mixtures thereof.
  • Pharmaceutical compositions of the present invention can be in a form suitable for topical use such as, for example, an aerosol, cream, ointment, lotion, dusting powder, or the like. Further, the compositions can be in a form suitable for use in transdermal devices. These formulations may be prepared, using a compound of formula (I), or a pharmaceutically acceptable salt thereof, via conventional processing methods. As an example, a cream or ointment is prepared by admixing hydrophilic material and water, together with about 5 wt % to about 10 wt % of the compound, to produce a cream or ointment having a desired consistency.
  • Pharmaceutical compositions of this invention can be in a form suitable for rectal administration wherein the carrier is a solid. It is preferable that the mixture forms unit dose suppositories. Suitable carriers include cocoa butter and other materials commonly used in the art. The suppositories may be conveniently formed by first admixing the composition with the softened or melted carrier(s) followed by chilling and shaping in molds.
  • In addition to the aforementioned carrier ingredients, the pharmaceutical formulations described above may include, as appropriate, one or more additional carrier ingredients such as diluents, buffers, flavoring agents, binders, surface-active agents, thickeners, lubricants, preservatives (including anti-oxidants) and the like. Furthermore, other adjuvants can be included to render the formulation isotonic with the blood of the intended recipient.
  • Compositions containing a compound of formula (I), or pharmaceutically acceptable salts thereof, may also be prepared in powder or liquid concentrate form.
  • Generally, dosage levels on the order of 0.01 mg/kg to about 150 mg/kg of body weight per day are useful in the treatment of the above-indicated conditions, or alternatively about 0.5 mg to about 7 g per patient per day. For example, obesity may be effectively treated by the administration of from about 0.01 to 50 mg of the compound per kilogram of body weight per day, or alternatively about 0.5 mg to about 3.5 g per patient per day.
  • It is understood, however, that the specific dose level for any particular patient will depend upon a variety of factors including the age, body weight, general health, sex, diet, time of administration, route of administration, rate of excretion, drug combination and the severity of the particular disease undergoing therapy.
  • The compounds of the invention may be used for treating diseases in which inhibition of DGAT1 is desirable, such as obesity.

  • The biological activity of the compounds of the invention may be tested in the following assay systems:
    • Evaluation of DGAT1 Enzyme Inhibition
  • DGAT assays for compound screening were carried out in 96-well round bottom plates in a total volume of 50 μl containing 25 mM Hepes pH 7.4, 150 mM NaCl, 2 mM MgCl2, 20 mM sodium fluoride, 1 mM dithiothreitol, 0.5 mg/mL BSA, 0.1% Triton X100, 200 uM DAG (1,2-dioleoyl-sn-glycerol) and 15 μM [14C] oleoyl CoA (specific activity 50-60 mCi/mmol) and a range of inhibitor concentrations in 1% DMSO. Reactions were initiated by the addition of human DGAT1 microsomes (0.4 μg/well) followed by incubation at 30° C. for 20 min. At the end of incubation, reactions were stopped by the addition of 5 μl 0.5N HCl, then 4 μl of each reaction was spotted directly onto a silica gel 60 (20×20 cm) TLC plate pre-scored to give twenty 1 cm wide lanes for lipid separation. Each lane was also spotted with 2 μl of carrier triglyceride (5 mg/mL) made up in chloroform/methanol (2:1 v/v mixture). After drying, the TLC plate was resolved over a distance of 15 cm in a solvent consisting of hexane, diethyl ether and acetic acid at a ratio of 80:20:1 v/v. The triglyceride spots were then located by iodine vapour staining.
  • Following chromatography, the triglyceride spots were cut out and placed in a scintillation vial for counting. The percentage inhibition values were calculated relative to control and where appropriate IC50 values were derived using the 4 parameter logistic model in XL fit. Generally compounds of the invention showed IC50 values below 5 μM, thus, for example, the compound of Example 114 showed an IC50 value of 1.8 μM and the compound of Example 137 showed an IC50 value of 1.3 μM.
  • The enzyme source used for the assay was prepared from Sf21 cells infected with baculovirus expressing human DGAT1. Full length human DGAT10RF (1467 bp) (Nucleotide Accession: NM 012079; Protein Accession: NP036211) was PCR amplified from human liver cDNA (Marathon Ready) and cloned into pFastBac HTa vector (Life Technologies) containing a 6-Histidine N-terminus. Subsequent baculovirus generation was carried out using Invitrogen's Bac to Bac system to yield optimal protein expression in Sf21 insect cells after 48 h of infection at a multiplicity of infection of 5 pfu/cell.
    • Preparation of Microsomes
  • Sf21 cells infected with human DGAT1 recombinant baculovirus were washed in ice-cold phosphate buffered saline and resuspended in a buffer containing 20 mM Hepes pH 7.5, 1 mM CaCl2, 1 mM MgCl2, 1 mM dithiothreitol and Complete Protease Inhibitor cocktail (Roche) 48 hours post infection. The suspended cells were allowed to swell on ice for 10 min after which time they were lysed with 15 strokes of a Dounce homogeniser (pestle B). Sucrose was then added to the lysate to a final concentration of 7.5% and the mixture was centrifuged at 1,500 g for 10 min at 4° C. The supernatant was collected and further centrifuged at 110,000 g for 1 h at 4° C. The resulting pellet, constituting the microsome fraction, was finally resuspended in 20 mM Hepes pH 7.5, 0.25M sucrose and Complete Protease Inhibitor and stored at −80° C. The protein concentration was determined using the Bio-Rad protein assay reagent kit.
    • Evaluation of Inhibition of Cellular Triglyceride Synthesis
  • The cell-based assay for DGAT is conducted with mouse 3T3L1 adipocytes. The 3T3L1 cells are grown in 24 well plates in DMEM supplemented with 10% FBS, Penicillin and Streptomycin. Triglyceride formation is determined in day 0 adipocytes by the addition of 0.25 μCi of [1 14C]-oleic acid (55 mCi/mmol) in the presence of a range of concentrations of inhibitors using DMSO as the carrier with a maximum DMSO concentration of 0.25%. After 16 h the cells are washed with PBS followed by lysis in 1 mM EDTA. The lysates are transferred to glass tubes and the lipids extracted by the addition of 2:1 (v/v) of chloroform:methanol and 1M H2SO4. The organic phase is removed, dried down and reconstituted in hexane. 4 μl of the reconstituted sample is then applied to silica coated TLC plates along with non-labelled triolein as carrier and standard. The TLC plates are developed in solvent system of n-hexane:diethyl ether:acetic acid (80:20:1). The plates are then exposed to iodine vapour, triglycerides spots visualised and marked before exposure of the plates to X-ray film. Following autoradiography, the triglyceride spots are excised from the TLC and counted by liquid scintillation counting. EC50 values are then determined as the inhibitor concentration at 50% of the dynamic range of the 14C dpm incorporation. Generally compounds showed EC50 values below 10 μM.
